"We got three comparable quotes, so even thought the price tag was high (yikes!), they seemed fair. Atlas Glen-Mor was responsive, thorough and professional. The two guys who installed the boiler (I think they were both named John) were great -- they worked hard all day (about 11 hours), explained everything very carefully, and were very professional. We needed a follow-up visit to skim the water in the boiler, and the service was prompt and effective. My only minor gripe is I've sometimes had to wait on hold for 10+ minutes when I've called, but I eventually get through. Maybe it's extra busy in winter time."

"The yearly service works out to be $50 a month. We've had two water heaters replaced through them because of a fault in them. They're usually very responsive. I like that I can request the service online. The only thing is, I wish that there was a better avenue for emergency services. If something doesn't work right away usually it takes a couple of days to get someone out and sometimes you can't wait two days without water."

Water Softeners FAQs, answered by experts

Yes. To get soft water, you can install a water softening system, which will replace the calcium and magnesium ions in the water with sodium or potassium ions. Water softeners cost anywhere from $200 to $6,000, depending on the size and complexity of the system. You can either install a water softener for the whole house or just at your shower heads. If you’re sensitive to sodium or potassium, you can install a salt-free water conditioner.

The average cost to install a water softener, including the system and labor, is approximately $1,500. However, the total price can range widely from $600 to $6,000. For some complete systems, the cost may be between $800 and $2,500. Labor for the installation typically costs between $150 and $1,000.

The final price is influenced by several factors, including:

  • System type, capacity, and complexity

  • Home size and household water demands

  • Water hardness levels

  • Accessibility of the installation site and the extent of plumbing work required

  • Whether new electrical work is needed

  • The professional hired and any local permit costs

Experts recommend that you put two to four bags of potassium chloride in your water softener every month. This amount depends on how much is in the bag (40 pounds is most common) and what your water softener manufacturer recommends. For more specific advice, talk to a water softener pro in your area and read the manual that came with your system.

Hard water isn’t necessarily bad for you. In some ways, it’s good for you. If you’re deficient in magnesium or calcium, hard water can give you a mineral boost that you wouldn’t get with soft water. However, this is where the benefits of hard water pretty much stop. Hard water can cause many minor inconveniences and lead to costly, premature replacements of your water-using appliances.

Drinking hard water is not known to have any negative health impacts. Using hard water can lead to dry skin and hair, and the minerals in hard water can build up in pipes, faucets, and appliances. Hard water is more of a threat to your plumbing than it is to your health.
